Due to rotational excitation, viscous shear of the oil and fluid causes heat to be generated, and this heat is transmitted to the spike 11 group @ Uke (1). *'il'Am increases in temperature. -〇kK spiral group bearing +11
The temperature at JFFFi is not uniform due to its heat transfer properties,
・The integral distribution is known as God. As a result, the spiral group bearing 11+ produces a love-like shape as shown in FIG. Due to this passionate form, the oil stroke in the operating state decreases at the outer periphery of the II hall 111, and as the amount of oil stroke decreases to a wide range of 1 mm, the bite becomes more effective. What was wrong with the lack of compatibility?

l is a thrust circle 4 (3) due to a key change due to a temperature rise on the bearing surface frust disk 131 side due to friction loss.
A convex deformation occurs on the 1 side, but at the same time, a concave deformation occurs due to the number of thrust W due to the pressure distribution generated from the thrust disk 131 (as shown in FIG. 8) due to the arrangement of the support (61). , this concave deformation easily occurs because the bearing... This makes it possible to suppress uneven deformation of the bearing (1) due to the rotation of the thrust disk (3).

時の耐焼き付き性の信慢性を向上できる効果がある。As described above, according to the present invention, in a thrust bearing device, the thermal deformation due to friction of the thrust bearing plate that abuts the rotating shaft from the axial direction and supports the lo1 rolling shaft is replaced by the deformation based on the thrust (thrust from the rotating shaft) M weight. The thrust bearing plate is supported from the opposite side of the rotating shaft so as to offset the rotational axis.Since it is equipped with a bearing support, it is possible to suppress the deformation that occurs in the thrust bearing plate during high load operation, and it is possible to suppress the deformation that occurs in the thrust bearing plate during high load operation. This has the effect of improving the reliability of anti-seizure properties.
